Questyle QP2R

Questyle QP2R is a well-designed and fine-crafted high-end portable player with excellent performance for enjoying the high-end and lossless music. QP2R, the second generation of Questyle's acclaimed digital audio players inherits Questyle's design and audio performance to experience top-tier portable music without compromise.

Four groups of Current Mode Amplifier circuits are located on both front and back of the PCB, which significantly shortens the distance that signals bypass on the PCB. Thus the audio performance is improved, which gives QP2R 0.0005% ultra-low distortion and less than 0.1Ω output impedance. Based on Current Mode Amplifier, QP2R is the first portable DAP in the world which uses pure Class A BIAS control system.

QP2R has preserved and inherited the typical and professional genes of Questyle which are becoming perfect over time. For the operating system, QP2R still uses Linux which has the inherent advantages on performance and stability over Android.

Portable high-resolution audio elation.

Pure Class A BIAS ControlPure Class control ensure QP2R operates only in the state of pure Class A when driving different loads, especially heavy loads, which achieves perfect listening experience.

Balanced Amplification DesignFour groups of Current Mode Amplifier circuits are located on both front and back of the PCB. A fully discrete and topological structure, achieves ultra-high sound performance close to recording level.

SystemCustomised battery of large capacity with more than 10 hours of battery life with a special chip used for accurate detection of battery level. Internal memory of 64GB and 2TB micro SD card for external expansion for more than ten thousand high-resolution songs.
